Let me try this
In order to solve this, we are going to use PEMDAS. If you have not heard of PEMDAS, it stands for parenthesis, exponents, multiplication, division, addition, subtraction. So, lets start with parenthesis. You would do parenthesis first. How do you do that? You just do the math in between the parenthesis. We would do exponents first. Its basically a number saying how much times to multiply the digit it is attached to. So, 3x3. We would then do subtraction, because multiplication, division nor addition is found next. 9-6 would be 3. Now, we would do multiplication next outside of the parenthesis. 3x4 = 12. Lets move on to division. 8 divided by 2 is 4. We would go to addition. 12+4 is 16. And lastly, subtraction. 16-5 is 11. The answer is 11.
Hope this helps.
